LED Lighting Design: detailed explanation of series lamps

'China Building Materials Network' in recent years with high power (HI-POWER) The advent of ultra-high brightness LED has greatly expanded the application field of LED, and is now widely used in entertainment, beautification of urban buildings, landscape lighting, etc, and is moving in the direction of daily lighting applications. For lighting designers and engineers, when designing LED lighting projects, it is necessary to first understand the performance characteristics, common specifications and application sites of various LED lamps, this post will follow the survey of the types of LED lamps that I opened earlier ~ Post, further describe the performance indicators, common specifications and their main applications of various types of LED lamps, and will be accompanied by illustrations. This post is completely free of charge, all colleagues are welcome to participate in the discussion. OK, I don't have much to say. First of all, let's talk about the widely used LED contour lights. First, the basic definition: LED contour lamp is also called guardrail lamp, digital tube, etc (The names of various manufacturers are different) , Mainly used to outline the appearance of buildings or other objects, its appearance resembles fluorescent tubes, and can be divided into O-shaped tubes and D-shaped tubes ( Note: There are also U-shaped, square, triangle, etc. , but not commonly used) The outer cover is generally made of PC material, which can prevent ultraviolet rays and high temperature; Second, the basic parameters: commonly used diameter specifications are generally ф 30, ф 50, ф 80, ф 100, ф 110, etc. , the color is generally milky white and transparent, the length is generally 500, 800, 1000, 1200, 1500, etc. It is generally customized according to the needs of the project. The number of built-in LED tubes is generally 99, 108, 144; Third, the control form: the contour lamp has two control modes: external control and internal control. The internal control does not need an external controller to change color, while the external control must be equipped with an external control controller to realize color change, at present, the applications on the market are still mostly outside control; IV. Main application occasions and achievable effects: LED contour lamps are controlled by microchips, it can realize flow effects such as gradual change, jump change, color flicker, random flicker, gradual change alternation, Chase, scanning, etc. It can also be combined into a screen through DMX control, to achieve the change effect of characters and patterns, at present, LED contour lamps are widely used in architectural outlines, overpasses, rivers, gardens, lampposts and other occasions, becoming an ideal choice for decorating the urban environment;
